Kev puas tsuaj los ntawm qhov hluav taws kub hauv qhov kev sib tw gravure yog ntsoog loj heev. Nyob rau hauv txoj kev tshwm sim dab tsi yuav tshwm sim no? Yuav zam tau li cas?
Kev kub nyhiab thiab tawg
Cov txheej txheem gravure txheej txheem yog hluav taws kub thiab tawg. Nws yog ib qho tshuaj sib xyaw ntawm cov organic solvents thiab cov pa oxygen. Nws yuav tsum muaj peb lub caij rau tib lub sijhawm:
1. VOC concentration nws siab tshaj 100% ntawm LEL, uas yog, tshaj qhov txo qis tawg.
2. Muaj qhov chaw tiv thaiv, uas yog, kub kub hauv qhov chaw tshaj qhov ntsuas ntawm qhov hnyav.
3. Muaj oxygen txaus nyob ze ntawm qhov chaw ntsim kub.
Tag nrho cov xwm txheej ntawm cov hluav taws yog qhov tshwm sim ntawm tib lub sijhawm ntawm peb lub caij tsim nyog. Cov kev ntsuas ua ntej yuav tsis muaj dab tsi ntau tshaj qhov tsis txhob muaj peb yam kev tsim nyog rau tib lub sijhawm. Vim tias cov pa oxygen feem ntau txaus, nws yog qhov qub kom tsis txhob muaj qhov xwm txheej tshwm sim ntawm thawj ob txoj kev mob, dua li ib qho tsis tshwm sim.
Dab tsi yog qhov ntau dua ntawm VOC nyob rau hauv lub gravure txheej rhiav yog dab tsi?
1. Sab hauv thiab sab saum toj ntawm tus number case los yog kua nplaum nplaum. Yog li, yog tias koj siv lub tshuab fais fab loj, koj yuav tsum siv lub tshuab pa tawg lossis lub tshuab tso cua.
2. Nyob ze lub tsho tiv no taub hau. Vim yog lub nplaub tshev ntawm tus txheej txheem ntawm tus txheej txheem, qhov chaw surrounding ntawm tus number case kua nplaum thiab cov phaj cov phom siab siab, thiab yog tias muaj electrostatic paug, nws yog yooj yim rau zes thiab hlawv.
3. Sab hauv qhov cub uas qhov chaw luam ntawv yog ze rau qhov chaw pub khoom noj. Hauv particular, feem ntau cov kuab tshuaj yog tam sim no cov kuab tshuaj ceev ziab, thiab qhov kub cua sov yog siab. Feem ntau ntawm cov kuab tshuaj ua kom qhuav hauv qhov cub nyob ze ntawm chaw nres nkoj. Cov concentration yog qhov siab tshaj plaws ntawm no. Yog hais tias tus nqi ntawm cov cua tsis txaus, lub txheej yog tuab. Ntau, nws muaj peev xwm tshaj qhov siab txo kev txwv.
Cwj pwm
1. Tshem tawm qhov hluav taws kub. Lub tsev luam ntawv tsis pub haus luam yeeb thiab lwm yam hluav taws qhib rau hauv qhov kev cob qhia. Feem ntau yog tshwm sim los ntawm hluav taws xob thiab hluav taws xob los ntawm kev sib tsoo los yog kev sib tsoo. Tshwj xeeb tshaj yog nyob rau saum toj no peb qhov chaw, yuav tsum tsis muaj sparks. Yog li, qhov cub hauv qab los yog kua nplaum, lub taub hau, thiab cov ntawv thov luam ntawv yuav tsum tau ntxuav tawm hauv qhov cub.
Nres tshem tawm zoo li yog tshem tawm qhov siab ntawm qhov chaw siab nyob rau ntawm qhov khoom. Tam sim no, nws muaj ib txoj hauv kev los ntawm tus neeg xyuas pib thiab txoj kev siv hluav taws xob tua hluav taws electrostatic. Txoj kev tshem tawm hluav taws xob electrostatic tawm yog tsim kom muaj qhov zoo thiab tsis zoo los ntawm lub tshuab hluav taws xob los ua kom tsis txhob muaj qhov voltage ntawm cov khoom, thiab lub tshuab hluav taws xob electrostatic yog cov txheej txheem tawm hauv kev ua haujlwm, yog li nws tsis tuaj yeem ze qhov chaw uas VOC concentration siab, thiab muaj ib qho kev txaus ntshai ntawm nws tus kheej. Tawm tswv yim rau kev saws me nyuam. Tus qauv ntawm tus neeg tsav tsheb yog kev lag luam thiab cov tswv yim, feem ntau siv tooj hlau hlau, tooj hlau xaim, ntawv ci txhuas ze rau cov khoom, los yog ntxiv ib qho txhuam ntawm electrostatic thiab tom qab lub raj xaim hlau los yog cov txhuam ntawm electrostatic. Qhov teeb meem uas yooj yim tshwm sim yog tias cov hlau xaim los yog txhuam ntawm electrostatic txhuam rau hauv av hlau los ntawm kab sib chaws los yog tus cob qhia cov phom. Hauv nruab nrab, lub rwb thaiv tsev yuav raug los ntawm kev xuas ntoo ntawm lub thawv, cov roj, los yog cov zoo li, los yog lub tshuab tua tus kheej yuav raug tshem tawm vim cov xaim av thiab qhov sib koom tes tawg. . Nws raug nquahu kom txuas nrog tooj liab los yog electrostatic txhuam thiab hauv av hlau ncaj nraim nrog tshwj xeeb thaiv.
Kev sib txhuam thiab hluav taws yog los ntawm kev sib tsoo lossis kev txhuam. Yav dhau los, cov xwm txheej tau tshwm sim thaum cov cua saum toj no poob thiab ntaus tus xaj ntim quav los ua cov txim taws thiab taws qhov xaj.
Thaum cov cua vaum nrov siab, qhov hluav taws xob hauv hluav taws xob nyob ntawm zaj duab xis los yog ntawv tau yooj yim los ntawm huab cua. Yog li ntawd, ua kom zoo ntub nyob rau hauv qhov kev cob qhia kuj yog ib lub luag haujlwm ntawm kev tshem tawm hluav taws xob.
2. Lub VOC concentration tswb raug ntsia rau hauv qhov cub. Thaum cov concentration siab dhau lawm, lub VOC concentration tswb yuav tau ceeb toom.
3. Nruab cov roj carbon dioxide tua hluav taws, thaum lub qhov hluav taws kub tuaj yeem yuav txau cov roj carbon dioxide.
4. Tsis txhob muab kua nplaum, ua kom hnyav thiab kua cwj pwm txav ze ntawm lub pob zeb, nws yog qhov zoo tshaj rau kev cais ntawm lub tshuab, kom tsis txhob muaj qhov hnyav ntawm thawb ntuag thiab cuam tshuam thaum muaj hluav taws ua ke, ua rau muaj kev sib tsoo loj . Nws yog qhov zoo tshaj kom ceev cov khoom siv tseg ntawm qhov chaw muaj kev txaus ntshai, thiab tsis ntau dhau lawm.
5. Xyuas kom tseeb tias cov cua nkag ntawm qhov cub tsis tuaj yeem qis dua tus nqi qis tshaj. Yam tsawg kawg ntawm huab cua ntim yuav tsum xyuas kom cov VOC concentration tsawg dua 25% ntawm LEL.
Gravure tshuab luam ntawv, txheej tshuab, thiab cov cav tov tshuab yuav tsis ua rau hluav taws thiab tawg nyob rau hauv ib txwm mob vim qhov loj npaum li cas ntawm huab cua nyob rau hauv thiab tawm. Qhov tshwm sim ntawm qhov hluav taws kub tawg yog feem ntau tshwm sim los ntawm qhov ntsuas kub tsis txaus, tus neeg teb xov tooj tsis kaw qhov qis thiab tso pa tawm tsawg heev, los yog cua qia cua tsis ua hauj lwm vim kab tsis ua hauj lwm los yog siv tawv tawg, thiab VOC ntsiab lus ntawm cov khoom loj.
6. Muaj qhov chaw ntim nyem rau ntawm qhov cub. Thaum qhov cub ntawm lub qhov cub nce mus rau ib qho twg, lub siab tawv qhov chaw nres nkoj cia li qhib, yog li ntawd qhov cub tsis tuaj yeem tawg.
